Prepare a separate space for the new cat, equipped with food, water, litter box, and toys, to allow them to adjust gradually to their new surroundings.

Introduce the new cat to existing pets gradually, starting with scent swapping and visual introductions before allowing direct interaction.

Supervise all interactions between the new cat and existing pets to prevent conflicts and ensure everyone feels safe and comfortable.

Use positive reinforcement, such as treats and praise, to reward calm and friendly behavior during introductions and interactions.

Be patient and allow each cat to adjust to the new dynamics at their own pace. Rushing the process can lead to stress and tension.

Offer hiding spots and elevated perches for the new cat to retreat to if they feel overwhelmed or need a break from social interactions.

Monitor the behavior of all cats closely during the introduction period and address any signs of aggression or distress promptly.
